AWSCloudWatchMonitoringObservabilita 5 min čtení

CloudWatch metriky, logy, alarmy, Logs Insights a Synthetics.

Custom Metriky¶

import boto3
cw = boto3.client('cloudwatch')
cw.put_metric_data(Namespace='MyApp', MetricData=[{
    'MetricName': 'OrdersProcessed',
    'Value': 42, 'Unit': 'Count',
    'Dimensions': [{'Name':'Environment','Value':'production'}]
}])

Logs Insights¶

fields @timestamp, @message
| filter @message like /duration/
| parse @message "duration=* ms" as duration
| sort duration desc
| limit 10

Alarmy¶

resource "aws_cloudwatch_metric_alarm" "high_cpu" {
  alarm_name          = "high-cpu"
  comparison_operator = "GreaterThanThreshold"
  evaluation_periods  = 3
  metric_name         = "CPUUtilization"
  namespace           = "AWS/EC2"
  period              = 300
  statistic           = "Average"
  threshold           = 80
  alarm_actions       = [aws_sns_topic.alerts.arn]
}

Shrnutí¶

CloudWatch = centrální monitoring hub AWS. Kombinujte s X-Ray (tracing) a Synthetics (canary tests).
